Bruce Banner has a tendency to get angry. And despite what he says, you really should like him when he gets angry — because if you don't, well, you're going to have a lot of problems with "The Avengers."

Joss Whedon, the man bringing Earth's Mightiest Heroes to the big screen, confessed in a recent interview that Banner's irritable alter ego, the Hulk, is easily the most challenging Avenger to get right. He might not be wrong, considering that it's taken three different actors to play the big green meanie on the big screen — Eric Bana in 2003's "Hulk," Ed Norton in 2008's "The Incredible Hulk" and, soon, Mark Ruffalo in "The Avengers." And Whedon's assertion certainly has the support of some of the Web's top comic book and movie commentators.

"Without a doubt, I think Hulk is the hardest 'Avengers' character to translate to the big screen," MTV Geek's Valerie Gallaher told MTV News about her "Avengers" character concerns. "Using CGI to create a character in a live-action film will end up looking like one big cartoon if not done right."

"Both Joss Whedon and Mark Ruffalo have a lot of pressure to give Bruce Banner and the Hulk two distinctive yet relatable characters," agreed Steve Sunu of Comic Book Resources. "Only time will tell if 'The Avengers' is an improvement for Hulk over 'The Incredible Hulk.' "

Of course, just because a challenge exists doesn't mean it's insurmountable.

's Kevin Polowy, who also agrees that Hulk presents Whedon's biggest challenge, has faith in the director's ability to do the Jade Giant justice. "I do have faith that if anyone can get it done, it's Joss Whedon," he said. "But compared to proven screen figures like Iron Man, Captain America and Thor, Hulk is far and away the trickiest pony in the bunch."

Not everyone is so concerned about Hulk. Caleb Goellner with Comics Alliance doesn't see the incredible menace as the most problematic character in "The Avengers"; like me, he assigns that role to the not-super-deadly duo of Black Widow and Hawkeye.

"They're going to be the hardest to portray," he said. "Black Widow got some exposure in 'Iron Man 2' and Hawkeye was teased in 'Thor,' but the 'master assassins' are at a disadvantage compared to Iron Man, Thor, Captain America and the Hulk. Their backstories will require considerable streamlining for them to make sense in this Marvel movieverse, so it will be interesting to see how much Joss Whedon and company will be able to fit in to an already packed movie.

"I suggest making them husband and wife, because that would be the cutest damn thing," Goellner added. Totally agreed, Caleb.
